Hi,
I use remoting in a Windows app... this remoting call a ServerA and using
ServerA get an object (marshaled) from ServerB... if I call a method on the
object gotten from ServerB and this ServerB has shut down it's service, I
get an exception and this exception stop the application event if it's
inside a try-catch structure... I mean, it does exactly the same as if it
was not in a try-catch structure. Is there a reason it's behaving this way?
I could send a code snippet, but it would not be useful... I get the ServerA
object, I get the ServerB object by calling a method on ServerA's object, I
open a try structure (try { ), I call a method on ServerB's object... if
the ServerB is running, everything is fine, if ServerB is not running, the
exception is thrown exactly the same way as if it were not in a try-catch
structure...
Why? and Is there a way around it?
Thanks

I solved this with a messaging structure ,,,,, if the server is shutting
down it will broadcast a message to the clients and vice versa .
maybe this is an idea for you to ??

ok, so I'm not the only one to get this behavior... Is this by design? I
mean, is it normal behavior?
Thanks for the messaging suggestion, I'll probably try to use it... ;)

Hello,
I am also experiencing this problem, although I would describe it as
follows:
- if you have a server application that experiences any kind of error,
you'd expect the error to be prolonged to the caller AppDomain, e.g.
back to the client. This *does* occur actually, however the server is
then terminated even if the client calls within try/catch brackets. Is
this what you see?
Further investigations brought me to a (not very elegant) solution. This
behaviour was introduced with .NET 2.0 due to a policy change for
unhandled exceptions in different threads than main (e.g. if you create
new objects on the server rather than using existing ones). If your
intention is to keep the service running, you have to open
machine.config and add this to the "runtime" tag:
<runtime>
<legacyUnhandle dExceptionPolic y enabled="true" />
</runtime>
This will keep the server running.
However, if any experts know more about this phenomenon or could supply
a more elegant way to solve this (like telling *only* the server to
behave like this), this would be very helpful.
I think this behaviour is generally positive as it points e.g. to
Windows Forms threading errors rather than just ignoring them and
possibly leading to an undefined application state. With remoting, I
always wondered why there were so few articles discussing this.
Best regards,
Helge

Is there any way to find out if a particular .net function will throw an

I am using structured exception handling i.e. try catch finally blocks with

Hi all,
The title of this post may sound a bit weird, but I was wondering about the
following nonetheless.
I have a class libray containing, say, 4 classes: A, B, C, D. Class A
somehow has a reference to B, B has a reference to C, and C to D.
If an exception happens in class D, I would like class A to get a
notification of this (all execution on classes B to D should be terminated).
I am wondering how to do this. The following seems...

While developing the below code I noticed that exceptions were not working as
expected. An exception is thrown inside an XML import DLL and not being

inside "theUI". Would anybody know why this is happening?
I thought the general rule for exceptions handling was the exception is
passed up the stack until the application handles it or the program
terminates?

it makes sense to throw an exception and when to use an alternate solution.
The .NET documentation recommends that an exception should be thrown only in
exceptional situations. It turned out that each of my colleagues had their
own interpretation about what an "exceptional situation" may actually be.
